Pérez Bustamante & Ponce

The tax team at Pérez Bustamante & Ponce can be noted for the variety of sectors in which it operates, including core areas in the Ecuadorian economy such as oil and gas and financial services, but also increasingly in the renewable energy sector. The group can also be highlighted for its strong focus on complex international tax matters, especially those related to transfer pricing. Practice head Juan Gabriel Reyes is often called upon for tax planning and structuring matters in Ecuador. Elsewhere, Carmen Simone-Lasso stands out for her work on the tax structure of financing projects; Juan Francisco Carrasco has a strong track record in front of local tax authorities; and up-and-coming partner Nicolás Maldonado specialises in advising clients on tax and family estate protection. More widely, the group is known for its ability to represent clients in tax matters before all courts, including highly complex constitutional tax matters before the Constitutional Court, such as those relating to tax applications, for which associate Gianella Gallegos stands out. Fellow associate Alejandro Páez is a specialist in tax optimization and advises both local and foreign clients. Since publication, Páez has been raised to the partneship - effective as of January 2026.
